Background of the Invention
Field of the Invention [0001]The present invention relates to a connecting member for removably connecting a plurality of pen needles to each other. The present invention further relates to an outer cover for a pen needle that facilitates connecting the pen needle to a drug delivery pen. The present invention still further relates to a cap for covering an outer cover of a pen needle.
Background of the Invention
[0002] In certain circumstances, it is desirable to inject medication directly into human tissue.
Typically, syringes or pen injection devices are used to inject medicaments into tissue areas, such as the intramuscular tissue layer, the subcutaneous tissue layer, and the intradermal tissue layer.
Typically, syringes or pen injection devices are used to inject medicaments into tissue areas, such as the intramuscular tissue layer, the subcutaneous tissue layer, and the intradermal tissue layer.
[0003] The assembly and operation of a typical pen injection device, as shown in FIGS. 1 and 2, is described in U.S. Patent Application Publication No. 2006/0229562, published on October 12, 2006.
[0004] Pen injection devices, such as the exemplary pen injector 100, as shown in FIG. 1, typically comprise a dose knob/button 24, an outer sleeve 13, and a cap 21.
The dose knob/button 24 allows a user to set the dosage of medication to be injected.
The outer sleeve 13 is gripped by the user when injecting medication. The cap 21 is used by the user to securely hold the pen injector device 100 in a shirt pocket, purse or other suitable location.
The dose knob/button 24 allows a user to set the dosage of medication to be injected.
The outer sleeve 13 is gripped by the user when injecting medication. The cap 21 is used by the user to securely hold the pen injector device 100 in a shirt pocket, purse or other suitable location.
[0005] FIG. 2 is an exploded view of an exemplary drug delivery pen shown in FIG. I.
The dose knob/button 24 has a dual purpose and is used to both set the dosage of the medication to be injected and to inject the dosed medicament via the lead screw 7 and stopper 15 through the medicament cartridge 12, which is attached to the drug delivery pen through a lower housing 17. In standard drug delivery pens, the dosing and delivery mechanisms are all found within the outer sleeve 13 and arc not described in greater detail here as they are understood by those knowledgeable of the prior art. The distal movement of the plunger or stopper 15 within the medicament cartridge 12 causes medication to be forced into the needle 11 of the hub 20. The medicament cartridge 12 is sealed by septum 16, which is punctured by a septum penetrating needle cannula 18 located within the hub 20. The hub 20 is preferably screwed onto the lower housing 17, although other attachment means can be used such as attaching to the cartridge. To protect a user, or anyone who handles the pen injection device 100, an outer cover 69, which attaches to the hub 20, covers the hub.
An inner shield 59 covers the patient needle 11 within the outer cover 69. The inner shield 59 can be secured to the hub 20 to cover the patient needle 11 by any suitable means, such as an interference fit or a snap fit. The outer cover 69 and inner shield 59 are removed prior to use. The cap 21 fits snugly against outer sleeve 13 to allow a user to securely carry the drug delivery pen 100.

The hub 20 is preferably screwed onto the lower housing 17, although other attachment means can be used such as attaching to the cartridge. To protect a user, or anyone who handles the pen injection device 100, an outer cover 69, which attaches to the hub 20, covers the hub.
An inner shield 59 covers the patient needle 11 within the outer cover 69. The inner shield 59 can be secured to the hub 20 to cover the patient needle 11 by any suitable means, such as an interference fit or a snap fit. The outer cover 69 and inner shield 59 are removed prior to use. The cap 21 fits snugly against outer sleeve 13 to allow a user to securely carry the drug delivery pen 100.
[0006] The medicament cartridge 12 is typically a glass tube sealed at one end with the septum 16 and sealed at the other end with the stopper 15. The septum 16 is pierceable by a septum penetrating cannula 18 in the hub 20, but does not move with respect to the medicament cartridge 12. The stopper 15 is axially displaceable within the medicament cartridge 12 while maintaining a fluid tight seal.
[0007] A pen needle, which includes the hub 20, needle 11, outer shield 69 and inner shield 59, is typically used for a single injection and is then disposed of.
Accordingly, patients must carry several pen needles to perform multiple injections over a period of time. Pen needles are generally stored loose in a container so that there is no simple and convenient way for a patient to keep multiple pen needles together. Accordingly, a need exists for removably connecting a plurality of pen needles together, thereby providing a patient with a convenient way to carry multiple pen needles.

Pen needles are generally stored loose in a container so that there is no simple and convenient way for a patient to keep multiple pen needles together. Accordingly, a need exists for removably connecting a plurality of pen needles together, thereby providing a patient with a convenient way to carry multiple pen needles.
[0008] Another problem a user encounters with drug delivery pens is difficulty in removing the packaging from the pen needle and attaching the pen needle to the drug delivery pen.
Typically, a foil seal covers the non-patient needle end of the outer cover and must be removed prior to connecting the pen needle to the drug delivery pen.
Additionally, the small size of the outer cover makes handling and connecting the pen needle difficult. Accordingly, a need exists for a pen needle that is easy to open and grip for the user.

Additionally, the small size of the outer cover makes handling and connecting the pen needle difficult. Accordingly, a need exists for a pen needle that is easy to open and grip for the user.
[0009]Another problem encountered by a user is having to handle the outer cover while trying to put the outer cover back on the hub assembly, which can lead to an accidental needle stick. Furthermore, the non-injection end of the needle is left uncovered, which can also lead to an accidental needle stick. An additional need exists for a cap for an outer cover that encloses the non-injection end of the needle with a puncture-resistant cap.
[0010] Following an injection, the used needle, or "sharps", must be properly disposed of.
Used sharps may become contaminated by body fluids and the like creating a hazard for anyone that may handle them following their use. Sharps disposal containers store the disposed sharps and prevent unintentional contact with any object disposed therein.
Accordingly, a further need exists for an outer cover that completely encapsulates the pen needle within a puncture resistant cover and cap after use.
Summary of the Invention
Used sharps may become contaminated by body fluids and the like creating a hazard for anyone that may handle them following their use. Sharps disposal containers store the disposed sharps and prevent unintentional contact with any object disposed therein.
Accordingly, a further need exists for an outer cover that completely encapsulates the pen needle within a puncture resistant cover and cap after use.
Summary of the Invention
[0011]ln accordance with an aspect of the present invention, a connecting member removably connects a plurality of pen needles together, thereby providing a convenient way for a patient to carry multiple pen needles.
[0012] In accordance with another aspect of the present invention, an outer cover of a pen needle has a shape and gripping members to facilitate handling by a user.
[00131In accordance with yet another aspect of the present invention, a cap has a first opening for receiving a first end of an outer cover of a pen needle and a second opening for receiving a second end of the outer cover.
